G. g. blood loss or pneumonia. The clinical features of chronic anaemia are discussed in Section 9: General Medicine. 9 Chronic anaemia due to other causes There are many causes of anaemia resulting from either: ■ Decreased production of either red blood cells or haemoglobin ■ Increased destruction of red blood cells.

The blood clotting mechanism involves a complex series of steps, or cascades, in which specific plasma proteins called coagulation factors are activated in sequence. g. Christmas Factor (Christmas was the name given to the first patient shown to have a deficiency of what is now known as Factor IX) and anti-haemolytic factor (Factor VIII). 10. fibrinogen: The major coagulant protein in plasma. Converted to (insoluble) fibrin by the action of thrombin. 7 on p. 28). Fibrinolysis During the normal haemostatic mechanism, the process of limiting the clot occurs through several mechanisms.

Haemoconcentration: Elevated haematocrit (packed cell volume) due to a reduction in plasma volume. A variation in either of these factors will affect the haemoglobin concentration. During pregnancy, for example, an apparent anaemia may exist simply as a result of an increase in plasma volume, but without any reduction in the total amount of haemoglobin present. This is called haemodilution. Since the overall capacity of blood to carry oxygen is unchanged, it is not necessarily a pathological state.
